16 J1587 Packet Detection Problem
The engine must be running for the IVG to retrieve vehicle data.
If the Core Data Items and J1939 Packet Detection tests passes, it’s not a problem if the
J1587 Packet Detection test fails. This indicates that the IVG system is getting its vehicle
data from the J1939 link. Some 2012 and newer trucks do not supply J1587 data.

To get J1587 data, a truck’s engine must supply J1587 data and a connection must be made
to the J1587 wires (power I/O cable). If data are not detected, check and reseat the power I/O
"Y" connections at the truck’s diagnostic plug.

Many newer trucks do not provide J1587 data. The IVG system auto-detects the data
bus, including J1587 bus traffic, and automatically select the most reliable data source for
vehicle data.
